Description

Locking structure with adjustable distance

Technical Field

The utility model relates to a locking limit structure's technical field, in particular to distance adjustable locking structure.

Background

The function test of the existing non-mapping test industry on the PCBA mainly comprises the steps of pressing a test probe on a test point on a product to be tested and a B2B connector, enabling the test probe to contact a pad on the product to be tested and a test point of B2B, providing a simulated operation environment for the PCBA, and obtaining parameters of all states to verify the function of the PCBA to be tested. In the FCT test process of the PCBA, the stability of the test must be ensured to ensure that the test probe can accurately and stably contact the test point of the PCBA, so that the test probe module and the carrier plate module are required to be accurately positioned and matched, and the test probe can accurately contact the test point.

Among the spacing buffering module of current equipment, use buffer and the spacing mode of screw usually, it is spacing to cushion the carrier position, guarantee that the support plate can cross reset to same position after the material loading at every turn, adopt the spacing mode of screw nut cooperation at the present moment, adjustment need use hexagonal spanner or open-ended spanner at every turn, can avoid driving the screw rotation when locking nut, cause the skew of limit position and then influence positioning accuracy, at screw terminal surface unevenness, cause the error easily.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that overcome prior art not enough, provide a simple structure, be convenient for daily debugging and maintain a distance adjustable locking structure that occupation space is few simultaneously.

The utility model adopts the technical proposal that: the utility model discloses a support plate, linear drive device, a plurality of slide rail and slip module, it is a plurality of the slide rail with linear drive device all sets up on the support plate, slip module all with a plurality of slide rail sliding fit, linear drive device's expansion end with the slip module is connected, still be provided with locking limit structure on the support plate, locking limit structure includes base, stop screw and locking screw, the base be provided with stop screw matched with screw hole, stop screw's one end with the spacing cooperation of slip module, still be provided with the fluting on the base, the locking screw passes the fluting with base locking cooperation.

Furthermore, the both sides of base are provided with the lug, all be equipped with the through-hole on the lug.

Furthermore, the limit screw and the matched end of the sliding module are planes.

Further, the open slot is communicated with the threaded hole.

Furthermore, a counter bore is formed in the base and matched with the locking screw.

Further, the diameter of the counter bore is larger than that of the locking screw.

The utility model has the advantages that: the utility model adopts a single locking component to limit and buffer the sliding module, has simple integral structure design, uses a single hexagonal wrench to debug and maintain at once, and reduces the daily operation and maintenance time and labor cost; the buffer parts and the limiting parts are reduced on the carrier plate, the overall occupied space of the equipment is small, and the space utilization rate is improved; the design of grooving and locking screw matching locking is adopted, the limiting screw after positioning is tightly pressed and fixed, secondary offset cannot occur, and positioning accuracy is guaranteed so that test positioning efficiency is improved.

Detailed Description

As shown in fig. 1 to 3, in this embodiment, the present invention includes a carrier plate (1), a linear driving device (2), a plurality of sliding rails (3) and a sliding module (4), wherein the plurality of sliding rails (3) and the linear driving device (2) are disposed on the carrier plate (1), the sliding module (4) is slidably engaged with the plurality of sliding rails (3), the movable end of the linear driving device (2) is connected to the sliding module (4), the carrier plate (1) is further provided with a locking and limiting structure (5), the locking and limiting structure (5) includes a base (51), a limiting screw (52) and a locking screw (53), the base (51) is provided with a threaded hole engaged with the limiting screw (52), one end of the limiting screw (52) is engaged with the sliding module (4) in a limiting manner, still be provided with the fluting on base (51), locking screw (53) pass the fluting with base (51) locking cooperation, the fluting, locking screw (53) with same size's hexagonal screw hole has all been seted up in spacing screw (52). The sliding module (4) is limited and buffered by the single locking assembly, the whole structure is simple in design, and debugging and maintenance are carried out immediately by using a single hexagonal wrench, so that the daily operation and maintenance time is shortened, and the labor cost is reduced; the carrier plate (1) is provided with a plurality of buffer parts and limiting parts, so that the occupied overall space of the equipment is small, and the space utilization rate is improved; the design of grooving and locking screw (53) matched locking is adopted, the locating screw (52) after locating is pressed and fixed, secondary offset cannot occur, and locating accuracy is guaranteed so that testing locating efficiency is improved.

In the embodiment, the two sides of the base (51) are provided with convex blocks, the convex blocks are provided with through holes, and the two groups of convex blocks are provided with inclination angles.
